The couple, who have been living apart amid rumours that their four-year marriage has come to an end, rode in a car together on Tuesday – around the same time the news broke that Khloé's mum Kris Jenner has separated from husband Bruce Jenner.

Khloé, 29, clearly turned to her husband in her moment of need, as her mum announced her separation from her husband of 22 years.

The reality TV star also took to Twitter to write about love, having been spotted at a Los Angeles club on Monday night with her wedding ring on.

"If I love u. Its a deep 4ever love," she tweeted. "Ride til the end. Family/friend. Its simply called love. I take it seriously. Dont judge unless u r in it."

Khloé's reunion with her hubby, after months of speculation that the pair have split, may be a sign that they are working through their differences.

Meanwhile, Kris and Bruce told E! News in a joint statement: "We are living separately and we are much happier this way."

"But we will always have much love and respect for each other. Even though we are separated, we will always remain best friends and, as always, our family will remain our number one priority."

A source close to the family told People, "There's actually no real drama. Bruce moved to Malibu in June and they liked that arrangement better. They just acknowledged they are separated."

Kris, 57, and Bruce, 63, have two daughters together — Kendall, 17 and 16-year-old Kylie — and four children each from previous relationships.

The couple wed in April 1991, one month after the Kardashian matriarch got divorced from her husband Robert Kardashian.
